4 years ago When also pullling https://github.com/sonyxperiadev/device-sony-yoshino/pull/161 and removing all USB related stuff from

Previously working on Don't know if it worked before or when, I have just bought a new USB C to Micro USB B cable and tried it the first time.
Description As a follow-up on https://github.com/sonyxperiadev/device-sony-yoshino/pull/159 I have bought a new cable to test audio via usb. When connecting a Sennheiser PXC 550 Headset (Micro USB B plug) via USB to my Yoshino/Lilac (USB C plug) trying to play audio is not working.
Probably because of following:
As a side note, the connected headset is being charged by the phone which is something I don't like. Looked around and found not too much how to disable that, the one thing I tried was:
dumpsys battery set -f usb 0it has not the effect of disabling delivering power to the headset.Symptoms No sound/audio via USB
How to reproduce Use a headphone with USB jack and connect it via USB to the phone, then play an audio file.
